N3 Payakumbuh – The presence of Bridge Ratapan Ibu located on Sudirman street Payakumbuh which was built in 1818 of 40 meters length with ancient architecture in the form of semicircular stone circle that is glued with lime and cement without using iron bone.

As one of the historical icon of struggle for Dutch colonization in Payakumbuh,  unfortunately at present time, the bridge’s condition is very poor and not well maintained. This is evident from the many creeping plants that hung on the water pipeline attached to the bridge.

Worse yet, on the western edge of the bridge grew banyan trees (Ficus Benjamina) as high as about one meter more. In the worry of this banyan grows bigger then the roots will penetrate and destroy this historic bridge.

Ir. Mulyadi Karo Karo, Lecturer and Chairman of Plantation Management Program at the State Agricultural Polytechnic Payakumbuh when confirmed by www.nusantaranews.net  about banyan plants at the campus Polytechnic Tanjung Pati (20/10) said, the existence of this banyan tree is very risky to the structure of the Bridge Ratapan Ibu.

"At the tip of the root there is a calyptra (root hood) that serves to protect the roots from mechanical damage when it penetrates the soil and rocks for nutrients. When the calyptra encounters obstacles such as rocks or walls then calyptra will release enzymes such as acidic liquids that can destroy the structure of the walls that block the development of roots, "he explained.

"If calyptra has entered into the gap and the gap is filled with water then gradually the roots will grow and develop and continue to push and damage the surrounding features that will cause a major crack in the bridge structure", continued Ir. Mulyadi

Observer of Luak Limopuluah Mr. Yudilfan Habib Dt. Monty deeply regretted the lack of authority concerns related to the preservation of the assets of this historic site. " "If this is outlined then the Bridge Ratapan Ibu will be broken and destroyed slowly”, said Engku Syntal as known. (Rahmat Sitepu)
